Detailed Description

Extracts outer surface (as vtkPolyData) of any dataset.

vtkDataSetSurfaceFilter is a general-purpose filter to extract boundary geometry (and associated data) from any type of dataset. Geometry is obtained as follows: all 0D, 1D, and 2D cells are extracted. All 2D faces that are used by only one 3D cell (i.e., boundary faces) are extracted. The filter will handle any type of dataset, including unstructured grids with non-linear cells. (See also vtkGeometryFilter for additional documentation and information - vtkGeometryFilter is the preferred filter to use in most cases and may be deprecated in the future.)

The filter only has only a few options: methods for passing through point and cell ids (to support picking); and controls for nonlinear cell subdivision. At this time vtkDataSetSurfaceFilter has the distinction of being able to process non-linear cells requiring subdivision. For this reason, vtkDataSetSurfaceFilter should be used with non-linear cells; otherwise vtkGeometryFilter should be used. (Note: by default this filter will delegate processing of linear vtkUnstructuredGrids to vtkGeometryFilter as vtkGeometryFilter is so much faster. And vtkGeometryFilter will delegate to vtkDataSetSurfaceFilter when it encounters nonlinear cells.)

Fast Mode

vtkDataSetSurfaceFilter is sometimes used to simply render a 3D dataset. In which case we only are concerned about an approximate representation of the data and not necessarily the true exterior surface. In that case, simply set the FastMode flag to true.

Currently FastMode is used when extracting surface from a structured dataset or when Delegation is true. When Delegation is true, the flag is passed on to vtkGeometryFilter (see vtkGeometryFilter:SetFastMode).

Warning

At one time, vtkDataSetSurfaceFilter was a faster version of vtkGeometryFilter when processing unstructured grids, however vtkGeometryFilter is now faster. Also, vtkDataSetSurfaceFilter typically uses more memory than vtkGeometryFilter. Consequently as a convenience to the user, vtkDataSetSurfaceFilter will delegate to vtkGeometryFilter when processing linear vtkUnstructuredGrids. This typically produces a 5-10x speed up. (See vtkGeometryFilter for more information.) This delegation can be disabled by setting the Delegation data member.

vtkDataSetSurfaceFilter will generally not preserve topological connectivity. In other words, the output polygonal primitives may not be connected although in the originating dataset the boundary entities (e.g., faces) may have been connected. This can result in issues for filters that expect proper topological connectivity (e.g., vtkQuadricDecimation or vtkFeatureEdges).

A key step in this algorithm (for 3D cells) is to count the number times a face is used by a cell. If used only once, then the face is considered a boundary face and sent to the filter output. The filter determines this by creating a hash table of faces: faces that are placed into the hash table a single time are used only once, and therefore sent to the output. Thus large amounts of extra memory is necessary to build the hash table. This obsoleted approach requires a significant amount of memory, and is a significant bottleneck to threading.

This filter may create duplicate points. Unlike vtkGeometryFilter, it does not have the option to merge points. However it will eliminate points not used by any output polygonal primitive (i.e., not on the boundary).

If 1 (the default), the nonlinear face is triangulated based on the midpoints. If greater than 1, the triangulated pieces are recursively subdivided to reach the desired subdivision. Setting the value to greater than 1 may cause some point data to not be passed even if no nonlinear faces exist. This option has no effect if the input is not an unstructured grid.
